The Port of Shanghai is not a single facility but an expansive harbor complex, with its primary modern operations anchored by the offshore Yangshan Deep-Water Port and the heavily active Waigaoqiao terminal zone. The Yangshan Deep-Water Port, connected to the mainland via the engineering marvel Donghai Bridge, handles the majority of the port's massive container throughput, utilizing fully automated gantry systems and deep-water berths to accommodate the largest mega-container ships operating globally.
